Sniper Elite 4 abandoned by Rebellion?

I realize that we went through the Christmas/New Year holidays. But those passed already, and it is now January 9.

I have seen no sign of a Rebellion staff member on these Sniper Elite 4 forums for over 3 weeks now. There are several questions that went unanswered for weeks, questions that usually a game developer would answer in their forum if other users didn't.

Has SE4 been formally abandoned to its own devices and only users support it now? If so, the only place were I see any user to user support activity is in the Steam forums. Here I see pretty much nothing. What happened?
